If: The 1st Conditional
1. What is the 1st conditional?
The 1st conditional is an ‘if’ phrase for cause and effect.
That means ‘if x happens, y will happen‘.
It uses the word ‘will’.
2. How to make the 1st conditional
The 1st conditional is made by:
- ‘if’ clause (if + present tense) + ‘will’ clause (will + base verb)
The ‘will’ clause looks the same as the future tense, although technically it is not.
*The base verb is the verb in its simplest form, with no ‘to’, ‘ing’, or past tense ending.
(if + present tense)
(will + base)
|if you do this||I will give you $10||If you do this, I will give you $10.|
|if you don’t eat||you will be hungry||If you don’t eat, you will be hungry.|
|if you are late||she will kill you||If you are late, she will kill you.|
|if you put water in hot oil||it will start a fire||If you put water in hot oil, it will start a fire.|
The ‘if clause’ can be placed at the start or at the end.
|‘if’ clause at start||‘if’ clause at end|
|If you don’t eat, you will be hungry.||You will be hungry if you don’t eat.|
|If you are late, she will kill you.||She will kill you if you are late.|

|0 conditional||1st conditional|
|If you press this button, the light turns on.||If you press this button, the light will turn on.|
|If a cat sees a mouse, it chases it.||If a cat sees a mouse, it will chase it.|
